Half life of radioactive isotope

Radioactive decay calculations inputting two activities at two different dates and/or times, the half life may be calculated this is a common calculation in nuclear counting laboratories for short lived isotopes it is often used to show that activity on an air sample is from. If 75% of any given amount of radioactive element disintegrates in 60 minutes, what is the half-life of the the element what is the half life period of uranium a radioactive isotope has the half-life of 20 days. Radioactive isotope one of two or more atoms with the same number of protons but a different number of neutrons with a nuclear composition measured as the proportion of the atoms in a radionuclide that decompose per unit of time, usually stated as the half-life of that particular isotope.

Since half life is a constant, the ratio of carbon 14 to nitrogen 14 provides a measurement of the age of a sample in the medical field, the radioactive isotope cobalt 60 has been used for radiotherapy to shrink tumors that will later be surgically removed, or to destroy cancer cells in inoperable tumors.

The half-life is basically the time required for half the atoms to undergo radioactive decay the half for most the radio isotopes is very short and these are never found in nature some of these naturally occurring elements are radioactive as they have very short. The half-life of a radioisotope is the time it takes for half the original number of atoms of the isotope to undergo nuclear decay (radioactive decay) some radioisotopes have very long half-lives, some have very short half-lives. Radioactive isotopes, also called radionuclides, are literally the isotopes that are radioactive most elements have equal number of protons and neutrons however, the atoms of an element may contain same numbers of protons but different numbers of neutrons in their nuclei these are called isotopes.
